Michael Novacek on Toothy Dino Discovery

Ira talks with Michael Novacek, author of Terra, paleontologist and curator at the American Museum of Natural History in New York, about a new fossil discovery. Researchers excavated a 100 million-year-old skull of a Nigersaurus and found it had a very unusual set of teeth.
